Description

High-efficiency heat energy utilization structure in the upper preheating zone of ceramic kiln

technical field

The utility model relates to a ceramic kiln, in particular to a high-efficiency heat energy utilization structure for a preheating zone on the ceramic kiln.

Background technique

The ceramic kiln includes drying area, dehumidification area, preheating area, firing area, rapid cooling area, slow cooling area and fast cooling area at the end of the kiln in sequence. When the hot air transmitted by the district kiln passes through the preheating district kiln, it is generally transmitted through the pipe above the kiln in the state of heat exchange with the external air, which will cause a large amount of heat loss, the heat utilization rate is not high, and energy saving Ineffective.

Utility model content

The technical problem to be solved by the utility model is to provide a high-efficiency heat utilization structure in the upper preheating zone of the ceramic kiln, which has a high heat utilization rate, can effectively avoid heat loss, and achieve a good energy-saving effect.

In order to solve the above technical problems, the technical solution of this utility model is to provide a high-efficiency heat energy utilization structure in the upper preheating zone of the ceramic kiln. At the bottom of the kiln in the preheating zone, there are several B hot gas channels, the tails of the A hot gas channel and all the B hot gas channels, respectively communicating with the hot gas channels at the upper and bottom of the kiln in the firing zone;

The hot gas output main pipe of the kiln in the slow cooling zone passes downwards through the front and rear sides of the kiln in the preheating zone, and is also connected with the tails of all B hot gas channels;

The head of the A hot gas channel communicates downward with the heads of all the B hot gas channels through the heat transfer pipe.

According to the high-efficiency heat utilization structure of the preheating zone on the ceramic kiln mentioned above, the heads of all B hot gas passages are connected with the hot gas passages at the bottom of the dehumidification zone.

The high-efficiency heat energy utilization structure of the upper preheating zone of the above-mentioned ceramic kiln, since A hot gas channel and B hot gas channel are respectively arranged along the upper part and the bottom of the preheating zone kiln, are transmitted from the kiln in the slow cooling zone and the kiln in the firing zone. The hot air is transmitted in the A hot air channel and the B hot air channel, with a high heat utilization rate, which can effectively avoid heat loss and achieve a good energy-saving effect.

Description of drawings

Below in conjunction with accompanying drawing and specific embodiment, the utility model is described in further detail.

detailed description

Referring to Figure 1-Figure 2, a high-efficiency heat energy utilization structure for the preheating zone on the ceramic kiln is provided. The ceramic kiln includes a drying zone, a dehumidification zone, a preheating zone, a firing zone, a rapid cooling zone, a slow cooling zone and In the fast cooling zone at the end of the kiln, along the upper part of the kiln in the preheating zone, there is a box-type A hot gas channel 1, and along the bottom of the kiln in the preheating zone, there are 7 B hot gas channels 2, A hot gas channel 1 and all The tail of the B hot gas channel 2 communicates with the hot gas channels at the upper and bottom of the kiln in the firing zone respectively;

The hot gas output main pipe 3 of the kiln in the slow cooling zone passes downwards through the front and rear sides of the kiln in the preheating zone, and is also connected with the tails of all B hot gas channels 2;

The head of the A hot gas channel 1 communicates with the heads of all the B hot gas channels 2 downwards through the heat transfer pipe 4 .

The heads of all B hot gas passages 2 communicate with the hot gas passage at the bottom of the dehumidification area.

In use, the hot gas transmitted from the kiln in the slow cooling zone and the kiln in the firing zone is transmitted in the A hot gas channel 1 and all the B hot gas channels 2, so as to avoid being in the state of heat exchange with the external air all the time, which can be effectively Reduce heat loss, and play a role in increasing heat and heat preservation for the kiln in the preheating zone, which can effectively prevent heat loss in the kiln in the preheating zone. At the same time, since the hot gas delivered by the hot gas channel of the kiln in the firing zone and the hot gas delivered by the hot gas output main pipe 3 of the kiln in the slow cooling zone are mixed in all the B hot gas channels 2, the first-stage heating of the hot gas is realized. When the hot air heated by the first-stage heating is sent to the heads of all the B hot-gas passages 2, it is mixed with the hot air sent in the A hot-air passage 1 through the heat transfer pipe 4 to realize the second-stage heating of the hot air, and the temperature is raised through the second-stage heating The hot air continues to be sent forward along the hot air channel at the bottom of the dehumidification area. The superimposed heating of the above-mentioned hot gas can utilize the heat energy of the kiln and play a better effect.

The above-mentioned embodiments are preferred embodiments of the present utility model, and all structures similar to the present utility model and the equivalent changes made should belong to the protection category of the present utility model.
